## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A330 series airplanes; Airbus Model A340-300 series airplanes; and Airbus Model A340-541 airplanes. This proposal would require lubrication of the upper and lower shortening mechanism (SM) link of the main landing gear, and consequent detection of resistance or blockage of the greaseway. Depending upon the resistance finding and upon whether or not the airplane has a certain modification, this proposal would require various other actions including unblocking the greaseway; accomplishing any necessary repairs; performing various inspections; and accomplishing the eventual replacement of the SM8 pin, if necessary. This action is necessary to prevent failure of the landing gear lengthening system, which could result in reduced controllability of the airplane on the ground during landing. This action is intended to address the identified unsafe condition.
